A PDF of John Hoffman's classic book, "The Art and Science of Dumpster Diving".
Since it's hosted on Scribd, you might have to start a Scribd account in order
to download it, but it's free and worth it for the other documents, magazines
and books you will find posted there.
This book tilted my world view on it's ear when I first read it 20 years ago...
I own 2 physical copies of it, as well as his 2002 follow-up book, "Dumpster
Diving: The Advanced Course (How to Turn Other People's Trash into Money,
Publicity, and Power)".
